      let me know below query will gives better performnce. if hints are not use query will degrade performance.

      SELECT /*+ ORDERED INDEX (b, jl_br_balances_n1) USE_NL (j b)
      USE_NL (glcc glf) USE_MERGE (gp gsb) */
      b.application_id ,
      b.set_of_books_id ,
      b.personnel_id,
      p.vendor_id Personnel,
      p.segment1 PersonnelNumber,
      p.vendor_name Name
      FROM jl_br_journals j,
      jl_br_balances b,
      gl_code_combinations glcc,
      fnd_flex_values_vl glf,
      gl_periods gp,
      gl_sets_of_books gsb,
